Installation Guidelines

• ESD Precautions: Always use a grounded wrist strap and anti-static mat when handling the module to prevent damage to sensitive electronic components.
• Power Down: Ensure the turbine control system is powered down and locked out before inserting or removing the module from the rack.
• Jumper Configuration: Verify all jumper settings for coil current and resistance match the specific application requirements before final installation.
• Environment: Ensure the control cabinet provides adequate ventilation and is free from excessive dust, moisture, or corrosive gases to maintain the specified operating temperature range.
• Cable Routing: Keep communication cables (Ethernet/RS485) separated from high-voltage power lines to minimize EMI interference.
